Regrouting in Knapp
Tiled areas in Knapp need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Shower grout that has worn away
- Stained grout that cleaning won’t shift
- Dirty, worn grout on a tiled floor
Aftercare tips
Looking after new joints is easy:
- Open a window or run the fan to clear steam
- Give the walls a quick rinse after use
- Stick to mild products for cleaning grout
- Don’t ignore a tile that feels loose
A squeegee or cloth over the tiles after use stops soap and water sitting on the grout. Run the extractor fan or open a window to help it dry out.
If grout in the shower is washing out, act soon. Every shower pushes more water into the gaps, and that water can reach the wall or the floor below.
About our regrouting in Knapp
Regrouting is normally paired with resealing. Grout is for the joints between tiles, but internal corners and edges flex, so they need flexible silicone instead. Renewing both together means nothing is left half-done. If you’re dealing with kitchen splashback grout stained by grease and grout that stays dark however much it’s cleaned, we can help, on bathroom floors, shower walls and wet rooms alike.
In a village or hamlet like Knapp, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Questions from Knapp
Is Knapp in your area for regrouting?
Yes, Knapp is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Chandlers Ford station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Are you fully insured?
Yes. Full insurance covers our work.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
Do you need regrouting in Knapp?
Strong cleaning products and hard scrubbing slowly erode grout. Some bleaches and acid descalers break grout down with repeated use, leaving the joints sunken and rough.
It’s worth asking for a quote if you see:
- Old grout in a dated colour
- Shower grout that has worn away
- Floor grout that has worn and darkened
- Splashback grout that has darkened
If you let a flat or house near Chandlers Ford station, stained grout drags a rental down, and regrouting between lets puts that right.
What to look for in a quote
- Whether they seal over old material or remove it
- Whether you can choose the colour

What affects the cost of regrouting
For a quick quote, just ask. The main things that affect it are:
- The type of sealant required
- The size of the job
- When we can work, for business premises
- Mould in or behind the old joints
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
When you call or email, it’s useful to know:
- Roughly how big the job is
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
Every job is quoted individually. Simply call 0345 464 0079 or send us an email and describe the job, and photos are welcome.
What we can’t put right
It helps to know what we cannot do:
- Loose tiles, which need refixing first
- Movement in a stud wall or floor
- Tiles that are chipped or split
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

Leave it or put it right?
Once grout cracks, water can get behind the tiling. Left alone, that water can loosen tiles or damage the wall, which turns a regrout into a retile. Dealing with it now keeps it small. Older cottages and farmhouses around Knapp can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What regrouting looks like in Knapp
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St Mark, timber floors under older bathrooms flex, so joints need a sealant that moves with them. For site and facilities teams at buildings such as Ampfield Church of England Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
